Patent DE-19523742-A1 (DE)
Title: Optical fibre alignment for gyro, modulator or switch
Inventor: YUHARA TOSHIYA
IPC: G02B6/30
Filed: 1995-06-29
Abstract: To give an alignment between optic fibres with axially asymmetrical refraction index distribution and between an optic fibre and an optic element, an image is taken of the optic fibre across the line of carried light with an appts. to give an enlarged picture. The distribution is established of a characteristic image for the radial positions of the optic fibre image from the enlarged picture.  The appts. is set to give the max. distribution of a characteristic image at the outer zones of the optic fibre. The alignment of the rotating direction round the centre axis of the optic fibre is measured, as the rotating axis from the distribution in the characteristic image after the setting action. The rotating direction is aligned with the optic fibre rotating section on the basis of the measured results. Also claimed is an optic fibre holding assembly with a holder (3) to take an optic fibre (2a, 2b), with a fibre rotating section (9a, 9b) to turn the fibre as required. Also claimed is an optic fibre array with a continuously produced optic fibre for a strand to be cut continuously, to be turned to give an axial shift in the required direction.
Patent DE-19527520-A1 (DE)
Inventor: SUN KAI CHIH-KAI
IPC: G11B21/12
Filed: 1995-07-27
Abstract: A single mechanism is used to launch and retract the read-write heads from the medium of a disk drive. The mechanism includes a retraction lever 91, a retraction lever lock 118, a mechanical biasing member 76, a disk 37, and a voice coil motor 16. During launch of the read-write heads, the mechanical basing member 76 balances the emf generated by the voice coil motor 16. After launch, the voice coil motor is used to rotate a retraction lever 91 and increase the potential energy in the mechanical biasing member 76. The retraction lever lock 118 then is used to store this built-up potential energy. If the drive later experiences a loss of power, the mechanism automatically retracts the read-write heads from the media. During retraction of the read-write heads, the stored mechanical energy is applied to the retraction lever 91, which then automatically retracts the read-write heads. In the preferred embodiment, the disk is contained within a cartridge. <IMAGE>

IPC: G06K13/10
Filed: 1995-10-27
Abstract: The separating device (I) has, for the stack (3) a magazine shaft (1) with a separating slot (20). The stack rests on two rows of rollers (60), with axes aligned at right angles to direction of separation, and the lowest card (30) is moved by a slide (4) on the bars (40) in the separation direction (VR) through the slot (20).

Title: Optical sensor with integrated laser diode
Inventor: BENDETT MARK P DR
IPC: G01N21/41
Filed: 1996-05-29
Abstract: An optical sensor (12) for chemical recognition or measurement in the environment comprises a laser diode light source (10), an integral waveguide (12) within which the beam is carried and a detector (28). The waveguide consists of a glass substrate (16) with a channel (18), enriched with rare metals and with reflectors (20, 22) at both ends.

Title: Image reconstruction method for computer tomograph in spiral scan mode
Inventor: WALLSCHLAEGER HEINRICH DIPL PH
IPC: G06T11/00
Filed: 1996-06-27
Abstract: The image reconstruction method for a computer tomograph (1) working in a spiral scan operation mode, includes the step of shifting an examination subject (P), accommodated on a patient examination table (6), and a measuring system, rotating around the patient examination table, relatively w.r.t. each other, during operation of the computer tomograph. The measuring system comprises an X-ray source (3) and one, to it oppositely arranged, radiation receiver (5), whereby during operation of the computer tomograph an X-ray bundle (4) is emitted by the X-ray source, which hits on the radiation receiver. Spiral weakening values (S) are measured during circulation of the measuring system around the examination subject, which are evaluated in a calculation unit (8).  A weighting method is used for the determination of weakening values (S( alpha ,  beta )) for the reconstruction of images of even body layers of the examination subject. The weighting method is utilized with a superimposition of spiral weighing factors, allowing for freely selectable parameters of amount of superimpositions, distance of the superimpositions, and intensity of contribution of each superimposition.
